Empirical formulae for (n,p) reaction cross-sections at 14–15MeV neutrons

Abstract

New empirical formulae for calculating the [Formula: see text] reaction cross-sections were obtained by using the EXFOR experimental data for the neutron energy 14–15[Formula: see text]MeV. Considering the average binding energy per nucleon and dependences of cross-section in the principal formula, we get empirical formulae for estimating the [Formula: see text] reaction cross-sections for 122 nuclei in the mass number range of [Formula: see text]. The EMPIRE 3.2 and TALYS 1.95 codes have been used to evaluate the [Formula: see text] cross-sections for the selected nuclei within the specified neutron energy. The comparison of calculated cross-sections from the present proposed formulae with those from codes and previous systematics reveals more accurate predictions of the experimental data.
